Type Mismatch:cannot convert from String to Date error

[Anonymous]

Hi,
I am getting the following error for the tmap configuration attached. Can anyone please advice me on how to go about this?
Many Thanks,

Manju, it is a bit tricky because the date has backslashes instead of forward slashes. This means you need to escape the backslashes when parsing the date.
You can use:
TalendDate.parseDate("MM\\dd\\yyyy",StringHandling.CHANGE(row1.Column4,"d",""))
and then format the output field as "MMddyyyy" in the tMap schema

Hi,
Thanks for your reply. There are no back slashes in the data.
The input data looks like this , ""d20120327""
So inorder to remove the extra "" i am using this, (StringHandling.CHANGE(row1.Column4,"\"","")
and then i need to remove d , so i am using StringHandling.CHANGE(StringHandling.CHANGE(row1.Column4,"\"",""),"d","")
So the actual string which i need to convert is "20120327"

In the expression editor , if i only provide
TalendDate.parseDate("YYYYMMDD",StringHandling.CHANGE(StringHandling.CHANGE(row1.Column4,"\"",""),"d",""))
i get ORA-00984: column not allowed here in the console.
if i give this
TalendDate.formatDate("yyyymmdd", TalendDate.parseDate("YYYYMMDD",StringHandling.CHANGE(StringHandling.CHANGE(row1.Column4,"\"",""),"d","")))
i get the type mismatch error.

Please guide me on this.

Many Thanks,
Manju

You can get rid of the TalendDate.formatDate because formatDate returns a string.
Enter this in the field
TalendDate.parseDate("yyyyMMdd",StringHandling.CHANGE(StringHandling.CHANGE(row1.Column4,"d",""),"\"",""))
and do the formatting in the schema on the tMap out.

Thanks.
When i do that, i am getting this error ,
ORA-00984: column not allowed here
Is it becoz the column in not nullable in DB?
In the tmap out, i have the column type as Date and format as "yyyymmdd"
Am i still missing something?

Many Thanks,

OK, well the good news is we have gotten past the Talend errors and have moved on to the database errors
I found a relevant thread, but it looks like you need to format your date output to: "yyyy-MM-dd HH:mm:ss"
https://community.talend.com/t5/Design-and-Development/resolved-Always-get-ora-00984-error-when-exec...
Either that or keep the output data type a string and use the following format in the expression:
TalendDate.formatDate("MM/dd/yyyy",TalendDate.parseDate("yyyyMMdd",StringHandling.CHANGE(StringHandling.CHANGE(row1.Column4,"d",""),"\"",""))
Curious to see which solution works.
